Abstract

RATIONALE

How caffeine (CAF) intake and warm-up music combination affect male taekwondo athletes' performance during simulated combat is yet unstudied.

OBJECTIVE

This study examined the potential synergistic effects of low dose of CAF and warm-up music on subsequent taekwondo combat outcomes.

METHODS

In a double-blinded, randomized, crossover study, 16 male taekwondo athletes performed simulated combats under six conditions: (a) control, (b) CAF without music (CAF + NM), (c) placebo without music (PL + NM), (d) CAF with music (CAF + M), (e) PL with music (PL + M), and (f) no supplement with music (NS + M). After warming-up, athletes rated their felt arousal (FAS). Perceived exertion (RPE), feeling scale (FS), FAS, and physical enjoyment (PACES) were determined after combat while mean (HR) and peak (HR) heart rate were determined for each bout. Each combat was analyzed to determine time-motion aspects and technical-tactical skills.

RESULTS

CAF + M shortened skip and pause times than CAF and music in single-use (p < 0.05), while extend attack time than other conditions (p < 0.001). Additionally, CAF + M increased attacks and defensive actions above that of single treatment conditions (all p < 0.05). Moreover, CAF + M improved FS and FAS post-combat than the other conditions (p < 0.001) and PACES compared to NS + M, PL + NM and PL + M conditions (p < 0.05). Similarly, CAF + M reduced HR and HR than the other conditions (p < 0.05).

CONCLUSION

Combining low dose of CAF and warm-up music could be an effective strategy to enhance taekwondo combat performance in male athletes.

摘要

理论依据

咖啡因（CAF）摄入与热身音乐相结合如何影响男性跆拳道运动员在模拟战斗中的表现尚未得到研究。

目的

本研究考察低剂量CAF和热身音乐对后续跆拳道战斗结果的潜在协同效应。

方法

在一项双盲、随机、交叉研究中，16名男性跆拳道运动员在六种条件下进行模拟战斗：（a）对照组，（b）无音乐的CAF（CAF + NM），（c）无音乐的安慰剂（PL + NM），（d）有音乐的CAF（CAF + M），（e）有音乐的PL（PL + M），以及（f）无补充剂有音乐（NS + M）。热身结束后，运动员对他们的感觉唤醒（FAS）进行评分。战斗结束后测定主观用力程度（RPE）、感觉量表（FS）、FAS和身体愉悦感（PACES），同时测定每回合的平均心率（HR）和峰值心率（HR）。对每次战斗进行分析以确定时间-动作方面以及技术-战术技能。

结果

与单次使用CAF和音乐相比，CAF + M缩短了跳跃和停顿时间（p < 0.05），而攻击时间比其他条件更长（p < 0.001）。此外，CAF + M的攻击和防御动作比单一治疗条件下更多（所有p < 0.05）。而且，与其他条件相比，CAF + M战斗后的FS和FAS有所改善（p < 0.001），与NS + M、PL + NM和PL + M条件相比，PACES有所改善（p < 0.05）。同样，与其他条件相比，CAF + M降低了HR和HR（p < 0.05）。
